When it comes to wearable tech, the conversation usually starts with the wrist — but lately, it’s moving to the finger.
Both smart watches and smart rings track health data and keep connected, but they do so in very different ways. If you’re trying to decide between the two, or you’re wondering why someone might wear both, this guide is for you.

They both help you stay connected to your health. But the experience, form factor, and even data quality can vary a lot.
